Magnetic phase diagram of the mn_x fe_2−x p_1−y si_y system

The phase diagram of the magnetocaloric Mn_x Fe_2−x P_1−y Si_y quaternary compounds was established by characterising the structure, thermal and magnetic properties in a wide range of compositions (for a Mn fraction of 0.3 ≤ x < 2.0 and a Si fraction of 0.33 ≤ y ≤ 0.60). The highest ferromagnetic...

Étude des performances du cycle frigorifique régénératif de Brayton utilisant un nouveau matériau composite Mn-Fe-P-Si avec hystérésis thermique comme milieu de travail

MnFeP(As, Ge, Si) series compounds are three kinds of MnFe-based magnetocaloric materials, which have giant magnetocaloric effect. In this work, the experimental characteristic curves of new style Mn-Fe-P-Si materials, numbered as 1: Mn_1.32Fe_0.67P_0.52Si_0.49, 2: Mn_1.37Fe_0.63P...
